StaticKinematicState Class Reference

---

Detailed Description

The StaticKinematicState object represents the base pose of an object. Objects that have access to the StaticKinematicState object include:

• X3DObject
• Cluster

The static kinematic state on objects is created when applying envelopes, deform-by-spine or deform-by-curve operators. Currently an object can only have one static kinematic state. It represents a snapshot of the pose of the object when the Envelope, DeformBySpine or DeformByCage operator was applied. It is also changed when doing Set Reference Pose in the Animate|Deform|Envelope menu (see the SetEnvelopeRefPoses command). If an object has all 3 operations applied on the same object they will all share the same static kinematic state. When doing a cage deform on top of an envelope for example the later operation will reset the static kinematic state. This means that it's usually better to be in the reference pose when adding these deforms ( ResetActor).

The static kinematic state on clusters is created when the cluster is translated, rotated or scaled by the movecomponentop MoveComponent operator . The static kinematic state is the transformation applied by the MoveComponent operator on the cluster. There is one or possibly two static kine state per move component on a cluster. Therefore you end-up with multiple static kine on a cluster if you transform the cluster many times. The second static kine state on the cluster is created when moving clusters in relative mode.

Example:

        using namespace XSI;
        Application app;
        Model root = app.GetActiveSceneRoot();

        Null myNull;
        root.AddNull( L"", myNull );

        KinematicState nullGlobalKineState(myNull.GetKinematics().GetGlobal());
        Parameter param(nullGlobalKineState.GetParameters().GetItem(L"posx"));
        param.PutValue( (double)4.0 );

        param = nullGlobalKineState.GetParameters().GetItem(L"posy");
        param.PutValue( (double)3.0 );

        X3DObject mySphere;
        root.AddGeometry( L"Sphere", L"MeshSurface", L"", mySphere );
        param = mySphere.GetKinematics().GetGlobal().GetParameters().GetItem(L"posz");
        param.PutValue( (double)2.0 );

        CRefArray deformers(1);
        deformers[0] = myNull;

        Envelope myEnvelop;
        mySphere.ApplyEnvelope( deformers, siUnspecified, siUnspecified, myEnvelop );
        app.LogMessage( mySphere.GetStaticKinematicState().GetClassIDName() );
